Description
Technical field
The utility model is related to environmental protection and energy-saving building Material Field, more particularly to a kind of high-permeability, tempered and low-radiation energy-conservation glass
Glass.
Background technology
Low radiation coated glass (" Low-E " glass) is that a kind of infrared ray to 4.5～25 μm of wavelength has compared with high reflectance
Coated glass.This coated glass has high light transmittance to visible ray, it is ensured that indoor daylighting, and has to far red light
Highly reflective, so as to accomplish that preventing glass from absorbing outdoor heat produces again heat radiation by the incoming interior of heat, and by indoor object
The heat of generation is reflected, and reduces the purpose of the heat radiation throughput of glass.So as to realize reducing building heating system
Cold energy consumption.The performance of Low-E glass is mainly by visible light transmissivity, shading coefficient and selects coefficient to weigh.Wherein：Hide
Positive coefficient, glass blocks or resists the ability of solar energy, and English is Shading Coefficient, and reality is by glass
Heat with by thickness be 3mm thickness normal glass heat and ratio.Coefficient is selected, it is that country holds that coated glass selects coefficient
Recognize, the important indicator of glass energy-saving type is weighed inside glass industry.Select coefficient=transmitance/shading coefficient.So, such as
The shading coefficient of fruit low-e glass is lower, it is seen that light transmission rate is higher, and its energy saving is better.Common single silver low-E energy-conservation glass
The selection coefficient of glass is 1.0～1.2, and the selection coefficient of double silver-colored low-E energy-saving glass is 1.2～1.5.
High-transparency list silver low radiation energy-saving glass in the market, it is primarily present following deficiency：
(1) the high-transparency Dan Yin of existing better performances, using the technology of plated film after first tempering.That is float glass process original piece tempering
Afterwards, then plated film is carried out, then carries out other processing.This mode of production is less efficient, mainly production when coating wire screening
To be carried out according to specific product size, it is impossible to reach the maximum load rate of plated film.Meanwhile, if this production model produces substandard products
Afterwards, sticking patch is not prompt enough, for the neat piece delivery date of product has certain impact.
(2) it is existing can tempering high-transparency list silver low radiation energy-saving glass, its mechanical properties strength not enough, in transportation
In need to carry out pad pasting protection to face.This kind of mode, substantially increases the cost of product, causes product price higher, no
Beneficial to promoting the use of for energy-conserving and environment-protective building materials.Further, since the mechanical performance of existing product is not enough, cause in cutting, edging etc.
In process, easily face is caused damage, cause the working (machining) efficiency of such product lowly, yield rate is relatively low.
(3) existing high-transparency can tempering list silver products face insufficient strength, therefore during tempering using face to enterprising
Row tempering.The heat time of this tempering mode product is longer, and edge is easily overheated.Easily there is imaging matter in product after tempering
Amount is poor, after product installs wall, the phenomenon of reflected image distortion easily occurs.And due to the heated time it is relatively long, institute
During producing, the energy consumption of unit product is higher, and production cost is relatively large.
Chinese patent application CN102336529A discloses a kind of transmittance toughenable low radiation glass and its manufacture method, its
Film layer structure in technical scheme is glass/SiNx/ZnSnO/ZnO/Ag/NiCr/ZnSnO/SiNx, although monolithic after tempering
The coated glass visible light transmissivity can reach 85%, but its reflectivity also has more than 8%, and can not realize that face is downward
Tempering, the photo-thermal of the product is also more poor than performance.
